“…VanderHeyden et al 2001;Orendovici et al 2003) but it is not always possible to use these pieces of equipment in the field (due to cost, technical support etc.). We can instead perform a microscopic analysis using light microscopy for ozone symptom validation (Vollenweider et al 2003), which is of higher quality than voucher analysis (Günthardt-Goerg, personal communication).…”

Surface ozone is considered to be a very phytotoxic gaseous air pollutant. Its negative impacts at both the cell and the organ level have been shown, mainly as a result of experiments. However, the demonstration of ozone negative impacts on native plants is not explicit. An assessment of ozone impact on vegetation and ecosystems using indicators based on ambient ozone concentrations is insufficient and assessment techniques based on internal ozone dose and on real plant damage are more appropriate. Such a possible technique is the mapping of ozone visible symptoms due to ozone influence. The ICP-Forest method concerning ozone visible symptoms and the assessment of ozone influence were applied for the purposes of this case study. The visible symptoms are characterized by a few typical signs. Nevertheless, the identification of visible symptoms in native conditions can be problematic and misleading conclusions could be drawn. Therefore it is necessary to complete the identification of visible symptoms with a validation in order to confirm ozone as the cause of plant injury.

“…However, these species if confirmed may prove to be of importance as potential bioindicators in their indigenous ranges. The presence of newly identified ozone bioindicators would be unsurprising given the growing body of evidence regarding the number of plant species that are yearly shown to be ozone-sensitive (Kohut et al 1997;Davison and Barnes 1998;Madkour and Laurence 2002;Orendovici et al 2003;US Department of Interior 2003). Of the two crop species, soy and sunflower, enormous areas of agricultural land are currently dedicated to their production in monoculture.…”

In Argentina no historical or present programs exist specifically assessing ecosystem health with respect to photochemical air pollution, although phytotoxic concentrations of near-ground ozone have been documented in recent years. Here we report our preliminary findings on field observations of ozone-like injury found in natural plant populations and agroecosystems late in the 2005 growing season in the Southern Hemisphere. Several possible ozone bioindicator plants which have not been previously documented were observed to exhibit foliar symptoms consistent with ozone-induced injury. Based on these results we intend to expand field surveys and complete the screening process for injury confirmation of the plant species described here. For this and future research we will be using controlled chamber studies based in the US. Continuous monitoring of tropospheric ozone does not currently take place in the region of central Argentina. The combined evidence provided by intermittent air quality sampling and the presence of ozone-like injury to vegetation indicates the need to establish air quality and ozone biomonitoring networks in this region.

“…Some plants are capable of activating oxidative pressure mitigation mechanisms, such as accumulation of anthocyanins (Styen et al, 2003), or tannins and other phenolic compounds (Vollenweider et al, 2003) which may determine colour changes (reddening or browning). In the presence of ozone these manifestations may occur earlier (Orendovici et al, 2003), but they cannot be considered suitable indicators of ozone stress. Reddening and browning, as well as discolorations linked to early aging processes, are frequent manifestations observed in field surveys and affect some of the most sensitive or most widespread species or groups of species (Rubus sp.…”

Within the European intensive forest monitoring programme, the native vegetation on permanent Level II plots has been monitored for visible ozone injuries. The main purpose of the programme is to assess the potential risks for the forest vegetation and the natural ecosystems at the intensive monitoring plots. During the first years of the programme the surveys were qualitative, reporting only the number and the name of the symptomatic species in selected Light Exposed Sampling Site. In 2003 a new plot design was tested, based on the distribution of a number of miniplots along the edge of the forest, so as to obtain quantitative findings about the occurrence and distribution of the symptoms. The problems that still persist are related to: (i) the forest edge assessed for ozone symptoms may have a different floristic composition from the Level II plot itself; (ii) the anthropic pressure and the disturbances affecting the forest edge alters the floristic composition; (iii) the variability of the plant composition in the forest edge, which makes comparability difficult between different sites; and (iv) the evaluation of symptoms in several species that have not yet been experimentally tested. Further difficulties are due to the fact that symptoms observed in the field are often aspecific and cannot, therefore, be attributed solely to the phytotoxic action of ozone. To improve the effectiveness of the European programme, it is necessary: (i) to individualise and select common sensitive plant species for homogeneous ecological regions; (ii) to enhance experimental activities to test the sensitivity of a large number of plant species.
